Product details
Overview
RCLAMP0504FBTCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of single 5V I/O or power lines in USB Type-C, USB PD, and industrial interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 7.5V (IPP = 24A), maintains <20mΩ dynamic resistance, and operates from –40°C to +125°C in a 1.6 × 1.6 mm DFN-6 package.
For engineers reviewing the RCLAMP0504FBTCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and peak current, low junction capacitance (12pF), and compatibility with 5V bus protection in high-speed data interfaces requiring minimal signal distortion.
Technical Context
RCLAMP0504FBTCT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (7.5V typ.) from 1A to 24A (tp = 8/20μs) due to decreasing RDS(on) under surge conditions.
The device protects one bidirectional line with a 5V working voltage (VRWM = 5V), features 12pF junction capacitance at VR = 5V, and achieves ±30kV contact/air ESD per IEC 61000-4-2 - critical for USB SuperSpeed and CC line robustness without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5 V - matches standard USB 2.0/Type-C VBUS and data line operating range |
| Clamping Voltage | 7.5 V at IPP = 24 A (tp = 8/20 μs) - ensures protected ICs (e.g., USB controllers) remain below absolute maximum ratings during surge |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial end equipment |
| Junction Capacitance | 12 pF at VR = 5 V, f = 1 MHz - enables use on USB 2.0, CC, and SBU lines without degrading signal rise/fall times |
| Dynamic Resistance | 18 mΩ (measured 1–24 A, tp = 8/20 μs) - contributes to flat clamping behavior and low voltage overshoot during fast transients |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive cabin modules, industrial gateways, and ruggedized IoT edge nodes |
Pinout & Package
RCLAMP0504FBTCT is housed in a Pb-free, RoHS-compliant 1.6 mm × 1.6 mm × 0.55 mm DFN-6 package with exposed thermal pad (no solder mask defined). All pins are surface-mount; marking includes "R05" and date code. Recommended land pattern follows Semtech's 0.30 mm pitch, 0.50 mm pad width layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three must be connected via low-inductance paths to maximize 24A pulse handling |
| 4, 5, 6 | IN | Protected line input - bidirectional connection point for 5V bus or data line; parallel routing required for full rating |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Enables flat clamping voltage (7.5V) across full 1–24A surge range - avoids voltage runaway seen in silicon avalanche TVS |
| Low dynamic resistance | 18 mΩ typical - minimizes IR drop during surge, preserving clamping accuracy and reducing thermal stress |
| Ultra-low junction capacitance | 12 pF - supports USB 2.0 (480 Mbps) and USB Type-C CC/SBU signaling without measurable eye diagram degradation |
| High-temperature clamping stability | Clamping voltage drift <0.5V from –40°C to +125°C - eliminates derating for industrial ambient conditions |
Applications
| USB Type-C CC Line Protection | USB 2.0 Data Line (D+/D–) Protection |
|---|---|
Use Scenario: Protecting configuration channel (CC) pins of USB Type-C receptacles against ESD events during cable insertion and hot-plug operations. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed between CC pin and USB controller, operating at DC–1 MHz bandwidth.

IC Role / Device Role / Timing Role: Input-side transient clamp on PMIC or LDO input, coordinating with upstream fuse and downstream decoupling. Use Value: Enables compact 1.6 × 1.6 mm footprint while sustaining 1120W peak pulse power and meeting IEC 61000-4-5 Level 3 (±1kV) compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| uClamp0504TCT | Same 5V VRWM, but uses silicon avalanche TVS architecture; clamping rises to 11.5V at 24A; 15pF capacitance | Limited to lower-speed interfaces where 4V higher clamping and +3pF capacitance are acceptable | Select uClamp0504TCT only if cost sensitivity outweighs clamping stability and signal integrity requirements |
| TPD4E004DRYR | Quad-channel 5V TVS array; per-channel 5.5V clamping at 1A; 10pF; not rated for 24A pulses | Suitable for multi-line board-level protection but lacks single-line energy handling for direct connector placement | Choose TPD4E004DRYR when protecting multiple 5V lines simultaneously with space-constrained routing, not for high-energy single-line defense |
Compared with uClamp0504TCT and TPD4E004DRYR, RCLAMP0504FBTCT uniquely combines 24A surge rating, 7.5V flat clamping, and 12pF capacitance in a single-line DFN-6 - making it the only option qualified for direct USB Type-C CC line and industrial 5V bus protection where both energy handling and signal fidelity are mandatory.

FAQ
What is the maximum peak pulse current rating for RCLAMP0504FBTCT?
RCLAMP0504FBTCT is rated for 24A peak pulse current (tp = 8/20μs) per IEC 61000-4-5. This rating is validated across its full operating temperature range (–40°C to +125°C) and corresponds to 1120W peak pulse power. The device maintains stable clamping performance at this level due to its FET-based architecture and low dynamic resistance.
Does RCLAMP0504FBTCT support bidirectional signal lines like USB CC or D+/D–?
Yes, RCLAMP0504FBTCT is inherently bidirectional and designed for placement on single-ended or differential 5V signal lines including USB Type-C CC, SBU, and USB 2.0 D+/D–. Its symmetrical clamping behavior (7.5V typ. in either polarity) and 12pF capacitance ensure minimal impact on signal integrity while providing full ±30kV IEC 61000-4-2 ESD protection.
How does RCLAMP0504FBTCT differ from traditional TVS diodes in clamping behavior?
RCLAMP0504FBTCT uses a triggered FET shunt instead of a PN-junction avalanche structure. As a result, its clamping voltage remains nearly constant (7.5V) from 1A to 24A surge current, unlike silicon TVS diodes whose clamping rises linearly with current (VC = VBR + IPP × RDYN). This eliminates voltage runaway during high-energy transients and improves system-level robustness.
What is the recommended PCB layout for optimal performance of RCLAMP0504FBTCT?
Place RCLAMP0504FBTCT within 3 mm of the protected connector. Connect all three GND pins (1, 2, 3) directly to a solid ground plane using ≥3 thermal vias. Route the protected line (pins 4, 5, 6) as a single short trace with controlled impedance. Avoid stubs or splits - parallel connection of all IN pins is mandatory to achieve full 24A rating and minimize parasitic inductance.
Is RCLAMP0504FBTCT compliant with RoHS and halogen-free standards?
Yes, RCLAMP0504FBTCT is fully RoHS-compliant and halogen-free per IEC 61249-2-21. Its DFN-6 package uses lead-free matte tin plating, UL 94V-0 molding compound, and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30°C/85% RH.
